Status/reliable network coverage?
I'm reacting on changes to the State of the network.
QNetworkAccessmanager seemed the solution, but a quick search showed that you use QNetworkConfigurationManager instead.
The onlineStateChanged signal seems to be unrealiable very well. I constantly receive when connectivity drops (I turn on airplane mode), but when it retrieves (I disable airplane mode) I do not receive the signal.
When I turn off the network once again I get the signal with online = true, followed by a second call with, online = false about 2 seconds later.
I also tried to subscribe to the events Changed/configurationAdded/removed, but those don't either did not help.
In this post, bps methods are mentioned, can someone give me a small extract how to subscribe to the bps network changes? Maybe they are more reliable than the Qt API.
It was easier than expected, I followed the instructions given in the bps API and Subscriber to network events where I use netstatus_get_availability()
bps_initialize(); subscribe(netstatus_get_domain()); netstatus_request_events(0);
void Class::event(bps_event_t *event) { // Handle events if (bps_event_get_domain(event) == netstatus_get_domain()) { qDebug() << "network event"; bool netAvail = false; netstatus_get_availability(&netAvail); qDebug() << "bps network availability" << netAvail; } }
Quite strange for the event QNetworkConfigurationManager is now published correctly, perhaps, he did not receive the events of the bps and my subscription sets.

Acer iconia a100 update fails "network coverage is currently poor."
My Acer Iconia A100 has Android 4.0.3 and all updates fail with the message:
Network coverage is currently low
but it is not 100%, and all other network functions work fine.
I see a LOT of problems, debate and questions with this same error on models Iconia tab, but so far no clear solution.
Is this one? or is this just an orphan machine?
Their support website lists nothing available for the A-100.
Your version is the latest for PA_CUS1.
the documentation is normally in the update zip file.

Iconia Tab A200 still stuck on 4.0.3 tells me my network coverage is too poor.
Hey everybody.
Good then as you can read in the title, I was stuck on version 4.0.3 which is pretty old now. Whenever I try to update it tells me my "network coverage is too poor," but I'm right next to my WiFi and the signal is strong.
I put the automatic check for updates, but I still can't get it. I tried other networks and still nothing. My tablet is now super slow and I'm really bored. Someone knows how to solve the problem of update?
Thank you.
This is because the update for the A200 and other servers first models have been closed. I have no idea why the error indicates the wireless signal is not good enough, no doubt, someone decided that it was better than "we provide are no longer updated.
You can still get the last set of software from the website, they support just is more integrated update process.

Printer has stopped working - status of network offline
My Officejet series 4600 (4622) worked well for almost two years with a USB connection. Yesterday I interrupted while he was printing a document (something I've done before), and then I could not do print again. The computer can detect the printer but says it is "not connected".
The powers of printer on / off power of the fine. He made copies. It is not blocked. His configuration of said network status page: Type of connection offline and Active: No.
Also the printer does not print with the laptop that we print occasionally. The laptop also says that the printer is not connected.
I tried turning power and off the computer, the printer (separately and together) and the router. I changed the printer cable for different ports on the printer and the computer. I got a new printer cable. I used the doctor scanning & printing to HP. I removed the printer and re - he added. I uninstalled the printer and re-installed driver software (the latest version). Nothing has worked.
Do I need a new printer, or y at - it a solution that I have not tried?
Thank you for your help... After posting my problem, I found that it was indeed a connection problem with the cable.

To check network coverage and queues requests
Hello
We develop a simple application with webservices.
I need check the coverage of the network before requesting Web services...
If the mobile is on the cover, I have to send the request.
If the mobile is not in the blanket, I at the request of the queue and I send the application when I had the network...
According to the documents, I have to use "class ofCoverageInfo and CoverageStatusListener '. '"
are there examples...?
Please let me know how to use these classes...
import net.rim.device.api.system.CoverageInfo; import net.rim.device.api.system.CoverageStatusListener; public class MyClass implements CoverageStatusListener { public MyClass() { CoverageInfo.addListener(this); } public void coverageStatusChanged(int arg0) { switch(arg0) { case(CoverageInfo.COVERAGE_DIRECT): //do something case(CoverageInfo.COVERAGE_MDS): //do something case(CoverageInfo.COVERAGE_NONE): //do something } } }

Unable to set status of network adapter
I wrote a basic script to connect to a virtual machine network status both connected & Connect at power on. The script seems to work perfectly without any error. However when I check a box of network system is always disabled. Here's the script:
#Script to connect a virtual machine network adapter
$cred = get-Credential
SE connect-VIServer server.domain.com - Credential $cred
$machines = get - VM
foreach ($machine in $machines)
{
All-NIC - NIC 'NIC 1' - Networkname 'Organization LAN' - StartConnected: $true - connected: $true
}
Disconnect-VIServer-confirm: $falseAs far as I know ownership NetworkAdapter needs a NetworkAdapter object instead of a name of a network card. So I changed your script to first get to the purpose of the network card.
#Script to connect a virtual machines network card $cred = Get-Credential Connect-VIServer server.domain.com -Credential $cred Get-VM | Get-NetworkAdapter | ` Where-Object {$_.Name -eq 'Network adapter 1'} | ` Set-NetworkAdapter -Networkname 'Organisation LAN' -StartConnected:$true -Connected:$true -Confirm:$false Disconnect-VIServer -Confirm:$false

Change the network connection speed and reliability of the emulator
Hello
I want to test my application in the State of the slow and unreliable network.
I wonder if we can change the speed of the emulator network connection? Or y at - it a tool that can help us to do this?
I'm also thinking about a simple proxy server which can regulate the speed of connection. And then my application connects to this server to test. This type of proxy server software exist?
Thanks in advance

I think that the best you can do is play with simulation--> network coverage options - see the simulation on the Simulator menu.

What is your signal when this happens? It shows that EDGE at least 3 bars? If this is not the case, try to reset the device by removing the battery for 1 minute. After restarting the device (~ 1-3 minutes), check the signal and try again
